Sony VGN-SZ491N Wifi
WiFi, or wireless internet, uses a piece of hardware in order to talk to your router and modem. Searching for a new adapter is simple because the only thing you have to know is what OS you are running on your laptop. You are better off buying a common WiFi USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. Most new Wifi adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the system will install the drivers automatically.
Chief elements of an ineffective wireless card
- The wireless adapter in your Sony laptop cannot see the SSID coming from your router
- The WiFi adapter driver gives errors when installing
- Your WiFi signal disconnects itself all the time
